title: Anther smuts of Caryophyllaceae: molecular analyses reveal further new species.
abstract: Recent collections of Microbotryum (Pucciniomycotina, Basidiomycota) specimens inhabiting anthers of different caryophyllaceous host plants were analysed using LM and electron microscopy, as well as molecular phylogenetic analyses using rDNA (ITS and LSU) sequences. The phylogenetic relationships of caryophyllaceous anther parasites are discussed. Three new species, Microbotryum adenopetalae, M. minuartiae, and M. silenes-acaulis, are described based on morphological, ecological, and molecular characteristics. New host plants are reported for Microbotryum dianthorum (Dianthus jacquemontii and Petrorhagia saxifraga) and M. lychnidis-dioicae (Cucubalus baccifer and Silene zawadskii). For Microbotryum violaceum, a neotype is selected.
